TheApple Campus is the formercorporate headquarters ofApple Inc. from 1993 until 2017, when it was largely replaced byApple Park (a.k.a. Apple Campus 2). The campus is located at1 Infinite Loop inCupertino, California, and remains an Apple office and lab space. Its design resembles that of a university, with the buildings arranged aroundgreen spaces.


Construction of the campus began in 1992 and was completed in 1993 by the Sobrato Development Company.[1] Its area is 850,000 square feet (79,000 m2). Prior to its construction, the land was occupied by the companyFour-Phase Systems (later acquired byMotorola).
The campus was originally used exclusively forresearch and development, with Apple's corporate headquarters remaining at Building 1 on 20525 Mariani Ave (also known as Mariani One).[2] At that time, its buildings were referred to as R&D 1–6. With the return ofSteve Jobs to Apple in 1997, the campus became the company's official headquarters, and its buildings were renamed "IL" instead of "R&D". Jobs also banned employees' pets from the building.[3]
On the night of August 12, 2008, a fire started on the second floor of the building Valley Green 6. The firefighters worked until morning to extinguish the fire. No injuries were reported, but the forty-year-old building suffered $2 million of fire damage.[4]


The Apple Campus is located on the southeast corner ofInterstate 280 and De Anza Boulevard and occupies 32 acres (130,000 m2)[5] in six buildings spread over four floors. Each building is numbered with one digit on the private U-shaped street Infinite Loop, so named because of the programming concept of aninfinite loop. The street, in conjunction with Mariani Avenue, actually does form a circuit (or cycle) that can circulate indefinitely. The main building has the address 1 Infinite Loop, Cupertino, California. Employees refer to these buildings as IL1 to IL6 for Infinite Loop 1–6. Beyond Infinite Loop, the whole Apple Campus occupies an additional thirty buildings scattered throughout the city.
Some of these buildings are leased (with an average rental cost of $2.50 per square foot).[6] The company controls more than 3,300,000 square feet (310,000 m2) for its activities in the city of Cupertino. This represents almost 40% of the 8,800,000 square feet (820,000 m2) of office space and facilities for research and development available in the city.
The Apple Campus had anApple Store, first opened in 1993—predating the modern Apple Store chain—and was, at the time, the only place in the world where Apple merchandise could be purchased, including T-shirts, mugs, and pens. It was the only part of the campus open to the public.[7] The store was closed on January 20, 2024, at 6:00pm.[8]
